Coronary vasomotor disorders (CVD) are characterized by transient hypercontraction of
coronary vascular smooth muscle cells, leading to hypercontraction of epicardial and/or …

There is an urgent need to identify electrocardiographic characteristics that differentiate the
“benign early repolarization pattern” from “malignant early repolarization.” In a previous …

Background: The long-term prognosis of patients with variant angina presenting with
aborted sudden cardiac death (ASCD) is unknown. Objectives: The purpose of this study …

Background Early repolarization pattern (ERP) has been proved to increase risk of
arrhythmia death in the general population, but its prognostic significance in patients with …

Background We will focus our attention in this article in the ECG changes of classical
Prinzmetal angina that occur during occlusive proximal coronary spasm usually in patients …

The coronary artery diseases (CAD) that can lead to the occurrence of a syncopal attack
include acute coronary syndrome, vasospastic angina, effort angina, and prior myocardial …

Background Several arrhythmogenic markers have been suggested as predictors for risk of
life-threatening arrhythmias during symptom-free periods in vasospastic angina (VSA), but …

Aims An early repolarization (ER) pattern is a risk factor for ventricular fibrillation (VF) in
certain diseases. However, it is unclear whether this association holds for patients with …

Early repolarization (ER) has been accepted as a benign ECG variant for decades. Two
seminal studies challenged this notion and have demonstrated that ER pattern is associated …

2724 NAM GB cardioverter defibrillator (ICD) implantation at the Asan Medical Center,
